Update: I decided to open up the game for free again for now -- feel free to
try it on the play page. The latest blog post brought in a lot of helpful
feedback, and one of the big takeaways is that the semi-temporary graphics
there now are turning off a lot of people. So I'll likely bring on an artist at some point and reconsider the Early Access thing again when that's in better shape.

The dev process was kinda prototype -> gameplay -> playtesting
-> graphics (in progress), so the gameplay's a lot farther along than the rest.

Infinitroid Forum: Bug Reports

Found a super-secret room with what looks like an unintended grub jump requirement. That is, a 1-height passage with a block under the entrance but not the exit. The power-up at the end of the room was Damage x2. I was able to make it to the damage power-up, but couldn't make it all the way back out.

Unfortunately, what was under the passage exit was spikes, so I ded, and couldn't screenshot >_<.
